摘要

Learning to play a musical instrument requires complex multimodal skills involving si-multaneous perception of several sensory modalities: auditory, visual, and somatosen-sory as well as the motor system. Musical training thus provides an adequate neu-roscientific model to study multimodal integration and plasticity in musical training. The aim of this study was to investigate the impact of short-term uni- and multimodal musical training on auditory-somatosensory integration and plasticity. Two groups of nonmusicians were musically trained. The first group (sensorimotor-auditory group, SA) learned to play a musical sequence on the piano, whereas the second one (auditory group, A) actively listened to and made judgments about the correctness of the mu-sic. The training-induced cortical plasticity effect was assessed by recording musically elicited mismatch negativity (MMN) from magnetoencephalographic (MEG) measure-ments before and after training. The SA group showed significant enlargement of MMN after training compared to the A group, reflecting greater enhancement of musical rep-resentations in auditory cortex after sensorimotor-auditory training compared to mere auditory training. This study demonstrates that the sensorimotor and auditory systems integrate and that this multimodal training causes cortical reorganizational changes in the auditory cortex over and above the changes introduced by auditory training alone.
